In a notice published in the Federal Register earlier this week, the Commodity Futures Trading Commission (“CFTC”) again reopened the period to comment on its proposed position limits and aggregation rules, in light of questions posed at an Agricultural Advisory Committee meeting in December.  The CFTC’s proposed rules, which we summarized here when they were first issued, would set position limits for 28 physical commodity contracts and economically equivalent swaps, including four energy contracts:  (1) NYMEX Henry Hub Natural Gas (NG); (2) NYMEX Light Sweet Crude Oil (CL); (3) NYMEX RBOB Gasoline (RB); and (4) NYMEX NY Harbor ULSD (HO).  The reopened comment period will close on January 22, 2015.
